<h2>Detailed Description</h2>
<p>The QTextDecoder class provides a state-based decoder.</p>
<p>A text decoder converts text from an encoded text format into Unicode using a specific codec.</p>
<p>The decoder converts text in this format into Unicode, remembering any state that is required between calls.</p>
<p>See also <a href="qtextcodec.html#makeDecoder">QTextCodec::makeDecoder</a>() and <a href="qtextencoder.html">QTextEncoder</a>.</p>

<h2>Member Function Documentation</h2>
<h3 class="fn"><a name="QTextDecoder"></a>QTextDecoder::QTextDecoder ( const <a href="qtextcodec.html">QTextCodec</a> * <i>codec</i> )</h3>
<p>Constructs a text decoder for the given <i>codec</i>.</p>
<h3 class="fn"><a name="dtor.QTextDecoder"></a>QTextDecoder::~QTextDecoder ()</h3>
<p>Destroys the decoder.</p>
<h3 class="fn"><a name="toUnicode"></a><a href="qstring.html">QString</a> QTextDecoder::toUnicode ( const char * <i>chars</i>, int <i>len</i> )</h3>
<p>Converts the first <i>len</i> bytes in <i>chars</i> to Unicode, returning the result.</p>
<p>If not all characters are used (e.g&#x2e; if only part of a multi-byte encoding is at the end of the characters), the decoder remembers enough state to continue with the next call to this function.</p>
<h3 class="fn"><a name="toUnicode-2"></a>void QTextDecoder::toUnicode ( <a href="qstring.html">QString</a> * <i>target</i>, const char * <i>chars</i>, int <i>len</i> )</h3>
<p>This is an overloaded member function, provided for convenience.</p>
<p>The converted string is returned in <i>target</i>.</p>
<h3 class="fn"><a name="toUnicode-3"></a><a href="qstring.html">QString</a> QTextDecoder::toUnicode ( const <a href="qbytearray.html">QByteArray</a> &amp; <i>ba</i> )</h3>
<p>This is an overloaded member function, provided for convenience.</p>
<p>Converts the bytes in the byte array specified by <i>ba</i> to Unicode and returns the result.</p>
